ARTICLE III

COVENANTS

Section 3.01 Maintenance of Payment Account. The Securities Administrator shall maintain the Payment Account established pursuant to Section 4.04 of the Sale and Servicing Agreement in accordance with the requirements of such Section. The Securities Administrator shall make all payments of principal of and interest on the Notes (subject to Section 3.03) as provided in Section 3.05 herein from monies on deposit in the Payment Account.

Section 3.02 Maintenance of Office or Agency. The Issuer will maintain an office or agency where, subject to satisfaction of conditions set forth herein, Notes may be surrendered for registration of transfer or exchange, and where notices and demands to or upon the Issuer in respect of the Notes and this Indenture may be served. The Issuer hereby initially appoints the Securities Administrator to serve as its agent for the foregoing purposes. If at any time the Issuer shall fail to maintain any such office or agency or shall fail to furnish the Securities Administrator with the address thereof, such surrenders may be made at the Corporate Trust Office and notices and demands may be made or delivered to the Corporate Trust Office, and the Issuer hereby appoints the Securities Administrator as its agent to receive all such surrenders, notices and demands.

Section 3.03 Money for Payments To Be Held in Trust; Paying Agent. As provided in Section 3.01, all payments of amounts due and payable with respect to any Notes that are to be made from amounts withdrawn from the Payment Account pursuant to Section 3.05 shall be made on behalf of the Issuer by the Securities Administrator or by the Paying Agent, based on information provided by the Securities Administrator to the Paying Agent and no amounts so withdrawn from the Payment Account for payments of Notes shall be paid over to the Issuer except as provided in this Section 3.03. The Securities Administrator shall calculate the amount to be distributed to each Class and, based on such amounts, the Securities Administrator shall determine the amount to be distributed to each Noteholder. All of the Securities Administrator's calculations of payments shall be based solely on information provided to the Securities Administrator by the Master Servicer pursuant to Section 3.01 of the Sale and Servicing Agreement. Neither the Securities Administrator nor the Indenture Trustee shall be required to confirm, verify or recompute any such information but shall be entitled to rely conclusively on such information. The Issuer hereby appoints the Securities Administrator as its initial Paying Agent.

The Issuer will cause each Paying Agent, other than the Securities Administrator, to execute and deliver to the Securities Administrator and the Indenture Trustee an instrument in which such Paying Agent shall agree with the Securities Administrator and the Indenture Trustee (and if the Securities Administrator or the Indenture Trustee acts as Paying Agent it hereby so agrees), subject to the provisions of this Section 3.03, that such Paying Agent will:

(i) hold all sums held by it for the payment of amounts due with respect to the Notes in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided and pay such sums to such Persons as herein provided;

(ii) give the Securities Administrator and the Indenture Trustee notice of any default by the Issuer of which it has actual knowledge in the making of any payment required to be made with respect to the Notes;

(iii) at any time during the continuance of any such default, upon the written request of either the Securities Administrator or the Indenture Trustee, forthwith pay to the Securities Administrator all sums so held in trust by such Paying Agent;

(iv) immediately resign as Paying Agent and forthwith pay to the Securities Administrator all sums held by it in trust for the payment of Notes if at any time it ceases to meet the standards required to be met by a Paying Agent at the time of its appointment;

(v) comply with all requirements of the Code with respect to the withholding from any payments made by it on any Notes of any applicable withholding taxes imposed thereon and with respect to any applicable reporting requirements in connection therewith; and

(vi) not commence a bankruptcy proceeding against the Issuer in connection with this Indenture.

The Issuer may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, by Issuer Request direct any Paying Agent to pay to the Securities Administrator all sums held in trust by such Paying Agent, such sums to be held by the Securities Administrator upon the same trusts as those upon which the sums were held by such Paying Agent; and upon such payment by any Paying Agent to the Securities Administrator such Paying Agent shall be released from all further liability with respect to such money.

Subject to applicable laws with respect to escheat of funds, any money held by the Securities Administrator or any Paying Agent in trust for the payment of any amount due with respect to any Note and remaining unclaimed for one year after such amount has become due and payable shall be discharged from such trust and be paid to the Issuer; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Issuer for payment thereof (but only to the extent of the amounts so paid to the Issuer), and all liability of the Securities Administrator or such Paying Agent with respect to such trust money shall thereupon cease; provided, however, that the Securities Administrator or such Paying Agent, before being required to make any such repayment, shall at the expense and direction of the Issuer cause to be published once, in an Authorized Newspaper published in the English language, notice that such money remains unclaimed and that, after a date specified therein which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining will be repaid to the Issuer. The Securities Administrator may also adopt and employ, at the expense and direction of the Issuer, any other reasonable means of notification of such repayment (including, but not limited to, mailing notice of such repayment to Holders whose Notes have been called but have not been surrendered for redemption or whose right to or interest in monies due and payable but not claimed is determinable from the records of the Securities Administrator or of any Paying Agent, at the last address of record for each such Holder).

Section 3.04 Existence. The Issuer will keep in full effect its existence, rights and franchises as a statutory trust under the laws of the State of Delaware (unless it becomes, or any successor Issuer hereunder is or becomes, organized under the laws of any other state or of the United States of America, in which case the Issuer will keep in full effect its existence, rights and franchises under the laws of such other jurisdiction) and will obtain and preserve its qualification to do business in each jurisdiction in which such qualification is or shall be necessary to protect the validity and enforceability of this Indenture, the Notes, the Mortgage Loans and each other instrument or agreement included in the Trust Estate.

Section 3.05 Payment of Principal and Interest. (a) On each Payment Date from amounts on deposit in the Payment Account, the Securities Administrator shall pay to the Persons specified below the Available Funds for such Payment Date; provided, however, any Corridor Contract Payments shall be distributed as set forth in Section 8.08.

(b) On each Payment Date, the Available Funds shall be distributed in the following order of priority, in each case to the extent of the Available Funds remaining for such Payment Date:

(viii) to the Holders of the Class B-3 Notes, the related Accrued Note Interest for such Class for such Payment Date.

(c) On each Payment Date, the Holders of each Class of Notes shall be entitled to receive payments in respect of principal equal to the Principal Distribution Amount for that Payment Date, allocated on a pro rata basis, based on the Note Principal Balances thereof, in reduction of the Note Principal Balances thereof, until the Note Principal Balances thereof have been reduced to zero.

(d) On each Payment Date, any Net Monthly Excess Cashflow shall be paid as follows, in each case to the extent of such remaining Net Monthly Excess Cashflow:

(i) to the Holders of the Notes, pro rata, in an amount equal to the Overcollateralization Increase Amount, payable to such Holders as part of the Principal Distribution Amount as described under Section 3.05(c) above;

(ii) sequentially, in the following order, to the Holders of the Class M-1, Class M-2, Class M-3, Class M-4, Class B-1, Class B-2 and Class B-3 Notes in an amount equal to the Allocated Realized Loss Amount for such Notes, to the extent not previously reimbursed;

(iii) sequentially, in the following order, to the Holders of the Class A-1, Class M-1, Class M-2, Class M-3, Class M-4, Class B-1, Class B-2 and Class B-3 Notes, any Basis Risk Shortfall Carry-Forward Amount for each such Class of Notes on such Payment Date to the extent not covered by any Corridor Contract Payments made under the related Corridor Contract pursuant to Section 8.08; and

(iv) any remaining amounts, including any Overcollateralization Release Amount for such Payment Date, will be distributed to the Certificate Paying Agent, as designee of the Issuer, for the benefit of the Holders of the Trust Certificates.

(e) Each distribution with respect to a Book-Entry Note shall be paid to the Depository, as Holder thereof, and the Depository shall be responsible for crediting the amount of such distribution to the accounts of its Depository Participants in accordance with its normal procedures. Each Depository Participant shall be responsible for disbursing such distribution to the Note Owners that it represents and to each indirect participating brokerage firm (a “brokerage firm” or “indirect participating firm”) for which it acts as agent. Each brokerage firm shall be responsible for disbursing funds to the Note Owners that it represents. None of the Indenture Trustee, the Note Registrar, the Paying Agent, the Depositor, the Securities Administrator or the Master Servicer shall have any responsibility therefor except as otherwise provided by this Indenture.

(f) On each Payment Date, the Certificate Paying Agent shall deposit in the Certificate Distribution Account all amounts received pursuant to Section 3.05(d)(iv) for the purpose of distributing such funds to the Certificateholders. The Certificate Paying Agent shall make distributions to the Certificateholders under the Trust Agreement as directed by the Securities Administrator hereunder.

(g) Any installment of interest or principal, if any, payable on any Note that is punctually paid or duly provided for by the Issuer on the applicable Payment Date shall, if such Holder shall have so requested at least five Business Days prior to the related Record Date, be paid to each Holder of record on the preceding Record Date, by wire transfer to an account specified in writing by such Holder as of the preceding Record Date or in all other cases or if no such instructions have been delivered to the Securities Administrator, by check to such Noteholder mailed to such ▇▇▇▇▇▇'s address as it appears in the Note Register in the amount required to be distributed to such Holder on such Payment Date pursuant to such ▇▇▇▇▇▇'s Notes;

provided, however, that the Securities Administrator shall not pay to such Holders any amount required to be withheld from a payment to such Holder by the Code.

(h) The principal of each Note shall be due and payable in full on the Final Scheduled Payment Date for such Note as provided in the forms of Note set forth in Exhibits A-1, A-2 and A-3 to this Indenture. All principal payments on the Notes shall be made to the Noteholders entitled thereto in accordance with the Percentage Interests represented by such Notes. Upon notice to the Securities Administrator by the Issuer, the Securities Administrator shall notify the Person in whose name a Note is registered at the close of business on the Record Date preceding the Final Scheduled Payment Date or other final Payment Date (including any final Payment Date resulting from any redemption pursuant to Section 8.07 hereof). Such notice shall to the extent practicable be mailed no later than five Business Days prior to such Final Scheduled Payment Date or other final Payment Date and shall specify that payment of the principal amount and any interest due with respect to such Note at the Final Scheduled Payment Date or other final Payment Date will be payable only upon presentation and surrender of such Note and shall specify the place where such Note may be presented and surrendered for such final payment. No interest shall accrue on the Notes on or after the Final Scheduled Payment Date or any such other final Payment Date.

Section 3.06 Protection of Trust Estate. (a) The Issuer will from time to time prepare, execute and deliver all such supplements and amendments hereto and all such financing statements, continuation statements, instruments of further assurance and other instruments, and will take such other action necessary or advisable to:

Section 3.26

Certain Representations Regarding the Trust Estate.

(a) With respect to that portion of the Collateral described in clauses (a) through (h) of the definition of Trust Estate, the Issuer represents to the Indenture Trustee that:

(i) This Indenture creates a valid and continuing security interest (as defined in the applicable UCC) in the Collateral in favor of the Indenture Trustee, which security interest is prior to all other liens, and is enforceable as such as against creditors of and purchasers from the Issuer.

(ii) In each case, within the meaning of the applicable UCC: (A) the Collateral described in clauses (a) through (c) constitute “deposit accounts” or “instruments,” as applicable; (B) the Collateral described in clause (d) constitutes “real property;” and (C) the Collateral described in clauses (f) through (h) constitute “general intangibles.”

(iii) The Issuer owns and has good and marketable title to the Collateral, free and clear of any lien, claim or encumbrance of any Person.

(iv) The Issuer has taken all steps necessary to cause the Indenture Trustee to become the account holder of the Collateral.

(v) Other than the security interest granted to the Indenture Trustee pursuant to this Indenture, the Issuer has not pledged, assigned, sold, granted a security interest in, or otherwise conveyed any of the Collateral.

(vi) The Collateral is not in the name of any Person other than the Issuer or the Indenture Trustee. The Issuer has not consented to the bank maintaining the Collateral to comply with instructions of any Person other than the Indenture Trustee.

(b) With respect to any Collateral in which a security interest may be perfected by filing, the Issuer has not authorized the filing of, and is not aware of any financing statements against, the Issuer, that include a description of collateral covering such Collateral, other than any financing statement relating to the security interest granted to the Indenture Trustee hereunder or that has been terminated. The Issuer is not aware of any judgment or tax lien filings against the Issuer.

(c) The Issuer has caused or will have caused, within ten days, the filing of all appropriate financing statements in the proper filing office in the appropriate jurisdictions under applicable law in order to perfect the security interest in all Collateral granted to the Indenture

Trustee hereunder in which a security interest may be perfected by filing. Any financing statement that is filed in connection with this Section 3.26 shall contain a statement that a purchase or security interest in any collateral described therein will violate the rights of the secured party named in such financing statement.

(d) The foregoing representations may not be waived and shall survive the issuance of the Notes.

Section 3.27 Allocation of Realized Losses. (a) Prior to each Payment Date, the Master Servicer shall determine, based solely on information provided to it by the Servicer, the total amount of Realized Losses that occurred during the related Prepayment Period.

(b) Any Realized Losses on the Mortgage Loans will be allocated or covered on any Payment Date as follows: first, to the Net Monthly Excess Cashflow, by an increase in the Overcollateralization Increase Amount for that Payment Date as provided in Section 3.05 hereof; second, in reduction of the Overcollateralized Amount until reduced to zero (meaning, no losses will be allocated to the Notes until the aggregate Note Principal Balance of the Notes equals the aggregate Scheduled Principal Balance of the Mortgage Loans); and third, to the Class B-3, Class B-2, Class B-1, Class M-4, Class M-3, Class M-2 and Class M-1 Notes, in that order, in each case in reduction of the Note Principal Balance thereof, until the Note Principal Balance thereof has been reduced to zero. All Realized Losses allocated to such Notes will be allocated in proportion to the Percentage Interests evidenced thereby. Realized Losses will not be allocated to the Class A-1 Notes.

(c) In addition, in the event that the Securities Administrator receives any Subsequent Recoveries from the Servicer, the Securities Administrator shall deposit such funds into the Payment Account in accordance with Section 4.04 of the Sale and Servicing Agreement. If, after taking into account such Subsequent Recoveries, the amount of a Realized Loss is reduced, the amount of such Subsequent Recoveries will be applied to increase the Note Principal Balance of the related Class of Notes with the highest payment priority to which Realized Losses have been allocated and not previously reimbursed through the payment of an Allocated Realized Loss Amount pursuant to Section 3.05(d)(ii) but not by more than the amount of Realized Losses previously allocated to such Class of Notes pursuant to this Section 3.27. The amount of any remaining Subsequent Recoveries will be applied to sequentially increase the Note Principal Balance of the Class of Notes, beginning with the Class of Notes with the related next highest payment priority, up to the amount of such Realized Losses previously allocated (but only to the extent not previously reimbursed through the payment of an Allocated Realized Loss Amount pursuant to Section 3.05(d)(ii)) to such Class of Notes pursuant to this Section 3.27. Holders of such Notes will not be entitled to any payment in respect of current interest on the amount of such increases for any Accrual Period preceding the Payment Date on which such increase occurs. Any such increases shall be applied to the Note Principal Balance of each Class of Notes in accordance with its respective Percentage Interest.

ARTICLE IV

THE NOTES; SATISFACTION AND DISCHARGE OF INDENTURE

Section 4.01 The Notes. Each Class of Notes shall be registered in the name of a nominee designated by the Depository. Beneficial Owners will hold interests in the Notes through the book-entry facilities of the Depository in minimum initial Note Principal Balances of $25,000 and integral multiples of $1,000 in excess thereof.

The Indenture Trustee and Securities Administrator may for all purposes (including the making of payments due on the Notes) deal with the Depository as the authorized representative of the Beneficial Owners with respect to the Notes for the purposes of exercising the rights of Holders of the Notes hereunder. Except as provided in the next succeeding paragraph of this Section 4.01, the rights of Beneficial Owners with respect to the Notes shall be limited to those established by law and agreements between such Beneficial Owners and the Depository and Depository Participants. Except as provided in Section 4.08 hereof, Beneficial Owners shall not be entitled to definitive certificates for the Notes as to which they are the Beneficial Owners. Requests and directions from, and votes of, the Depository as Holder of the Notes shall not be deemed inconsistent if they are made with respect to different Beneficial Owners. The Securities Administrator may establish a reasonable record date in connection with solicitations of consents from or voting by Noteholders and give notice to the Depository of such record date. Without the consent of the Issuer and the Securities Administrator, no Note may be transferred by the Depository except to a successor ▇▇▇▇▇▇▇▇▇▇ that agrees to hold such Note for the account of the Beneficial Owners.

In the event the Depository Trust Company resigns or is removed as Depository, the Depositor may appoint a successor Depository. If no successor Depository has been appointed within 30 days of the effective date of the Depository's resignation or removal, each Beneficial Owner shall be entitled to certificates representing the Notes it beneficially owns in the manner prescribed in Section 4.08.

The Notes shall, on original issue, be executed on behalf of the Issuer by the Owner Trustee, not in its individual capacity but solely as Owner Trustee, authenticated by the Securities Administrator and delivered by the Securities Administrator to or upon the order of the Issuer.

Section 4.02 Registration of and Limitations on Transfer and Exchange of Notes; Appointment of Note Registrar and Certificate Registrar. The Issuer shall cause to be kept at the office of the Note Registrar (which shall be the office specified in Section 3.02) a Note Register in which, subject to such reasonable regulations as it may prescribe, the Note Registrar shall provide for the registration of Notes and of transfers and exchanges of Notes as herein provided.

Subject to the restrictions and limitations set forth below, upon surrender for registration or transfer of any Note at the office specified in Section 3.02, the Issuer shall execute and the Note Registrar shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes in authorized initial Note Principal Balances evidencing the same Class and aggregate Percentage Interests.

Subject to the foregoing, at the option of the Noteholders, Notes may be exchanged for other Notes of like tenor and in authorized initial Note Principal Balances evidencing the same Class and aggregate Percentage Interests upon surrender of the Notes to be exchanged at the office specified in Section 3.02. Whenever any Notes are so surrendered for exchange, the Issuer shall execute and the Securities Administrator shall authenticate and deliver the Notes which the Noteholder making the exchange is entitled to receive. Each Note presented or surrendered for registration of transfer or exchange shall (if so required by the Note Registrar) be duly endorsed by, or be accompanied by a written instrument of transfer in form reasonably satisfactory to the Note Registrar duly executed by the Holder thereof or his attorney duly authorized in writing with such signature guaranteed by a commercial bank or trust company located or having a correspondent located in the city of New York. Notes delivered upon any such transfer or exchange will evidence the same obligations, and will be entitled to the same rights and privileges, as the Notes surrendered.

No service charge shall be made for any registration of transfer or exchange of Notes, but the Note Registrar shall require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any registration of transfer or exchange of Notes.

The Issuer hereby appoints the Securities Administrator as (i) Certificate Registrar to keep at the office of its designated agent as specified in Section 3.02, a Certificate Register pursuant to Section 3.04 of the Trust Agreement in which, subject to such reasonable regulations as it may prescribe, the Certificate Registrar shall provide for the registration of Certificates and of transfers and exchanges thereof pursuant to Section 3.04 of the Trust Agreement and (ii) Note Registrar under this Indenture. The Securities Administrator hereby accepts such appointments.

Section 4.03 Mutilated, Destroyed, Lost or Stolen Notes. If (i) any mutilated Note is surrendered to the Securities Administrator, or the Securities Administrator receives evidence to its satisfaction of the destruction, loss or theft of any Note, and (ii) there is delivered to the Securities Administrator such security or indemnity as may be required by it to hold the Issuer, the Indenture Trustee and the Securities Administrator harmless, then, in the absence of notice to the Issuer, the Note Registrar or the Securities Administrator that such Note has been acquired by a bona fide purchaser, and provided that the requirements of Section 8-405 of the UCC are met, the Issuer shall execute, and upon its request the Securities Administrator shall authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Note, a replacement Note; provided, however, that if any such destroyed, lost or stolen Note, but not a mutilated Note, shall have become or within seven days shall be due and payable, instead of issuing a replacement Note, the Issuer may pay such destroyed, lost or stolen Note when so due or payable without surrender thereof. If, after the delivery of such replacement Note or payment of a destroyed, lost or stolen Note pursuant to the proviso to the preceding sentence, a bona fide purchaser of the original Note in lieu of which such replacement Note was issued presents for payment such original Note, the Issuer and the Securities Administrator shall be entitled to recover such replacement Note (or such payment) from the Person to whom it was delivered or any Person taking such replacement Note from such Person to whom such replacement Note was delivered or any assignee of such Person, except a bona fide purchaser, and shall be entitled to recover upon the security or indemnity provided therefor to the extent of any loss, damage, cost or expense incurred by the Issuer, the Indenture Trustee or the Securities Administrator in connection therewith.

Upon the issuance of any replacement Note under this Section 4.03, the Issuer may require the payment by the Holder of such Note of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other reasonable expenses (including the fees and expenses of the Securities Administrator) connected therewith.

Every replacement Note issued pursuant to this Section 4.03 in replacement of any mutilated, destroyed, lost or stolen Note shall constitute an original additional contractual obligation of the Issuer, whether or not the mutilated, destroyed, lost or stolen Note shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Notes duly issued hereunder.

The provisions of this Section 4.03 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes.

Section 4.04 Persons Deemed Owners. Prior to due presentment for registration of transfer of any Note, the Issuer, the Securities Administrator, the Paying Agent and any agent of the Issuer or the Securities Administrator may treat the Person in whose name any Note is registered (as of the day of determination) as the owner of such Note for the purpose of receiving payments of principal of and interest, if any, on such Note and for all other purposes whatsoever, whether or not such Note be overdue, and none of the Issuer, the Indenture Trustee, the Securities Administrator, the Paying Agent or any agent of the Issuer, the Indenture Trustee or the Securities Administrator shall be affected by notice to the contrary.

The Issuer may at any time deliver to the Securities Administrator for cancellation any Notes previously authenticated and delivered hereunder which the Issuer may have acquired in any manner whatsoever, and all Notes so delivered shall be promptly cancelled by the Securities Administrator. No Notes shall be authenticated in lieu of or in exchange for any Notes cancelled as provided in this Section 4.05, except as expressly permitted by this Indenture. All cancelled Notes may be held or disposed of by the Securities Administrator in accordance with its standard retention or disposal policy as in effect at the time unless the Issuer shall direct by an Issuer Request that they be destroyed or returned to it; provided, however, that such Issuer Request is timely and the Notes have not been previously disposed of by the Securities Administrator.

Section 4.06 Book-Entry Notes. The Notes, upon original issuance, will be issued in the form of typewritten Notes representing the Book-Entry Notes, to be delivered to The Depository Trust Company, the initial Depository, by, or on behalf of, the Issuer. The Notes shall initially be registered on the Note Register in the name of Cede & Co., the nominee of the initial Depository, and no Beneficial Owner will receive a Definitive Note representing such Beneficial Owner's interest in such Note, except as provided in Section 4.08. With respect to such Notes, unless and until definitive, fully registered Notes (the “Definitive Notes”) have been issued to Beneficial Owners pursuant to Section 4.08:

(i)

the provisions of this Section 4.06 shall be in full force and effect;

(ii) the Note Registrar, the Indenture Trustee, the Paying Agent and the Securities Administrator shall be entitled to deal with the Depository for all purposes of this Indenture (including the payment of principal of and interest on the Notes and the giving of instructions or directions hereunder) as the sole holder of the Notes, and shall have no obligation to the Beneficial Owners of the Notes;

(iii) to the extent that the provisions of this Section 4.06 conflict with any other provisions of this Indenture, the provisions of this Section 4.06 shall control;

(iv) the rights of Beneficial Owners shall be exercised only through the Depository and shall be limited to those established by law and agreements between such Owners of Notes and the Depository and/or the Depository Participants.

(v) whenever this Indenture requires or permits actions to be taken based upon instructions or directions of Holders of Notes evidencing a specified percentage of the Note Principal Balances of the Notes, the Depository shall be deemed to represent such percentage with respect to the Notes only to the extent that it has received instructions to such effect from Beneficial Owners and/or Depository Participants owning or representing, respectively, such required percentage of the beneficial interest in the Notes and has delivered such instructions to the Securities Administrator and the Indenture Trustee, as required by this Indenture.

Section 4.07 Notices to Depository. Whenever a notice or other communication to the Note Holders is required under this Indenture, unless and until Definitive Notes shall have been issued to Beneficial Owners pursuant to Section 4.08, the Indenture Trustee or Securities Administrator, as applicable, shall give all such notices and communications specified herein to be given to Holders of the Notes to the Depository, and shall have no obligation to the Beneficial Owners.

Section 4.08 Definitive Notes. If (i) the Depositor advises the Securities Administrator in writing that the Depository is no longer willing or able to properly discharge its responsibilities with respect to the Book-Entry Notes and the Depositor is unable to locate a qualified successor within 30 days or (ii) the Depositor, at its option (with the consent of the Securities Administrator, such consent not to be unreasonably withheld) elects to terminate the book-entry system through the Depository, then the Securities Administrator shall request that the Depository notify all Beneficial Owners of the occurrence of any such event and of the availability of Definitive Notes to Beneficial Owners requesting the same. Upon surrender to the Securities Administrator of the typewritten Notes representing the Book-Entry Notes by the Depository, accompanied by registration instructions, the Issuer shall execute and the Securities Administrator shall authenticate the Definitive Notes in accordance with the instructions of the Depository. None of the Issuer, the Note Registrar or the Securities Administrator shall be liable for any delay in delivery of such instructions and may conclusively rely on, and shall be

protected in relying on, such instructions. Upon the issuance of Definitive Notes, the Securities Administrator shall recognize the Holders of the Definitive Notes as Noteholders.

In addition, if an Event of Default has occurred and is continuing, each Note Owner materially adversely affected thereby may at its option request a Definitive Note evidencing such Noteholder's interest in the related Class of Notes. In order to make such request, such Noteholder shall, subject to the rules and procedures of the Depository, provide the Depository or the related Depository Participant with directions for the Securities Administrator to exchange or cause the exchange of the Noteholder's interest in such Class of Notes for an equivalent interest in fully registered definitive form. Upon receipt by the Securities Administrator of instructions from the Depository directing the Securities Administrator to effect such exchange (such instructions to contain information regarding the Class of Notes and the Note Principal Balance being exchanged, the Depository Participant account to be debited with the decrease, the registered holder of and delivery instructions for the Definitive Note, and any other information reasonably required by the Securities Administrator), (i) the Securities Administrator shall instruct the Depository to reduce the related Depository Participant's account by the aggregate Note Principal Balance of the Definitive Note, (ii) the Securities Administrator shall execute, authenticate and deliver, in accordance with the registration and delivery instructions provided by the Depository, a Definitive Note evidencing such Noteholder's interest in such Class of Notes and (iii) the Securities Administrator shall execute and authenticate a new Book-Entry Note reflecting the reduction in the Note Principal Balance of such Class of Notes by the amount of the Definitive Notes.

Section 4.09 Tax Treatment. The Issuer has entered into this Indenture, and the Notes will be issued with the intention that, for federal, state and local income, single business and franchise tax purposes, the Notes will qualify as indebtedness. The Issuer and the Securities Administrator (in accordance with Section 6.06 hereof), by entering into this Indenture, and each Noteholder, by its acceptance of its Note (and each Beneficial Owner by its acceptance of an interest in the applicable Book-Entry Note), agree to treat the Notes for federal, state and local income, single business and franchise tax purposes as indebtedness. The Issuer shall be a "U.S. person" (as that term is used in Section 1.1441-4(a)(3)(ii) of the United States Treasury regulations) for United States federal income tax purposes.

Section 4.10 Satisfaction and Discharge of Indenture. This Indenture shall cease to be of further effect with respect to the Notes except as to (i) rights of registration of transfer and exchange, (ii) substitution of mutilated, destroyed, lost or stolen Notes, (iii) rights of Noteholders to receive payments of principal thereof and interest thereon, (iv) Sections 3.03, 3.04, 3.06, 3.09, 3.17, 3.19 and 3.20, (v) the rights, obligations (to the extent applicable to the provisions of the Indenture remaining in effect) and immunities of the Indenture Trustee and Securities Administrator hereunder (including the rights of the Indenture Trustee and Securities Administrator under Section 6.07 and the obligations of the Securities Administrator under Section 4.11), and (vi) the rights of Noteholders as beneficiaries hereof with respect to the property so deposited with the Indenture Trustee payable to all or any of them, and the Indenture Trustee, on demand of and at the expense of the Issuer, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture with respect to the Notes and shall release and deliver, or cause the Custodian to deliver, the Collateral to or upon the order of the Issuer, when:

(A)

either:

(1) all Notes theretofore authenticated and delivered (other than (i) Notes that have been destroyed, lost or stolen and that have been replaced or paid as provided in Section 4.03 hereof and (ii) Notes for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Issuer and thereafter repaid to the Issuer or discharged from such trust, as provided in Section 3.03) have been delivered to the Securities Administrator for cancellation; or

(2) all Notes not theretofore delivered to the Securities Administrator for cancellation

a.	have become due and payable,
b.	will become due and payable at the Final Scheduled Payment Date within one year, or
c.	have been called for early redemption and the Trust has been terminated pursuant to Section 8.07 hereof,

and the Issuer, in the case of (2)a. or (2)b. above, has irrevocably deposited or caused to be irrevocably deposited with the Securities Administrator, cash or direct obligations of or obligations guaranteed by the United States of America (which will mature prior to the date such amounts are payable), in trust for such purpose, in an amount sufficient to pay and discharge the entire indebtedness on such Notes then outstanding not theretofore delivered to the Securities Administrator for cancellation when due on the Final Scheduled Payment Date or other final Payment Date and has delivered to the Securities Administrator and the Indenture Trustee a verification report from a nationally recognized accounting firm certifying that the amounts deposited with the Securities Administrator are sufficient to pay and discharge the entire indebtedness of such Notes, or, in the case of (2)c. above, the Issuer shall have complied with all requirements of Section 8.07 hereof,

(B) the Issuer has paid or caused to be paid all other sums payable hereunder; and

(C) the Issuer has delivered to the Indenture Trustee an Officer's Certificate and an Opinion of Counsel, each meeting the applicable requirements of Section 10.01 hereof, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied with and, if the Opinion of Counsel relates to a deposit made in connection with Section 4.10(A)(2)b. above, such opinion shall further be to the effect that such deposit will constitute an “in-substance defeasance” within the meaning of Revenue Ruling 85-42, 1985-1 C.B. 36, and in accordance therewith, the Issuer will be the owner of the assets deposited in trust for federal income tax purposes.

Section 4.11 Application of Trust Money. All monies deposited with the Securities Administrator pursuant to Section 4.10 hereof shall be held in trust and applied by it, in

accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent or the Issuer, Certificate Paying Agent as designee of the Issuer, as the Securities Administrator may determine, to the Holders of Securities, of all sums due and to become due thereon for principal and interest or otherwise; but such monies need not be segregated from other funds except to the extent required herein or required by law.

Section 4.12

[Reserved].

Section 4.13 Repayment of Monies Held by Paying Agent. In connection with the satisfaction and discharge of this Indenture with respect to the Notes, all monies then held by any Person other than the Securities Administrator under the provisions of this Indenture with respect to such Notes shall, upon demand of the Issuer, be paid to the Securities Administrator to be held and applied according to Section 3.05 and thereupon such Person shall be released from all further liability with respect to such monies.

Section 4.14 Temporary Notes. Pending the preparation of any Definitive Notes, the Issuer may execute and upon its written direction, the Securities Administrator may authenticate and make available for delivery, temporary Notes that are printed, lithographed, typewritten, photocopied or otherwise produced, in any denomination, substantially of the tenor of the Definitive Notes in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Notes may determine, as evidenced by their execution of such Notes.

If temporary Notes are issued, the Issuer will cause Definitive Notes to be prepared without unreasonable delay. After the preparation of the Definitive Notes, the temporary Notes shall be exchangeable for Definitive Notes upon surrender of the temporary Notes at the Corporate Trust Office of the Securities Administrator, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Notes, the Issuer shall execute and the Securities Administrator shall authenticate and make available for delivery, in exchange therefor, Definitive Notes of authorized denominations and of like tenor, class and aggregate principal amount. Until so exchanged, such temporary Notes shall in all respects be entitled to the same benefits under this Indenture as Definitive Notes.

Section 4.15 Representation Regarding ERISA. By acquiring a Note or interest therein, each Holder of such Note or Beneficial Owner of any such interest shall be deemed to represent that either (1) it is not acquiring the Note with Plan Assets or (2) (A) the acquisition, holding and transfer of such Note will not give rise to a nonexempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code and (B) the Notes are rated investment grade or better and such person believes that the Notes are properly treated as indebtedness without substantial equity features for purposes of the Department of Labor regulation 29 C.F.R. § 2510.3-101, and agrees to so treat the Notes. Alternatively, regardless of the rating of the Notes, such person may provide the Securities Administrator and the Owner Trustee with an Opinion of Counsel, which Opinion of Counsel will not be at the expense of the Issuer, the Depositor, the Seller, any Underwriter, the Owner Trustee, the Indenture Trustee, the Securities Administrator, the Master Servicer or the Servicer which opines that the acquisition, holding and transfer of such Note or interest therein is permissible under applicable law, will not constitute or result in a non-exempt prohibited transaction under ERISA or Section 4975 of the Code and will not subject the Issuer,

the Seller, the Depositor, any Underwriter, the Owner Trustee, the Indenture Trustee, the Securities Administrator, the Master Servicer or the Servicer to any obligation in addition to those undertaken in the Indenture and the other Basic Documents.

ARTICLE V

DEFAULT AND REMEDIES

Section 5.01 Events of Default. The Issuer shall deliver to the Indenture Trustee, within five days after learning of the occurrence of an Event of Default, written notice in the form of an Officer's Certificate of any event which with the giving of notice and the lapse of time would become an Event of Default under clause (iii), (iv) or (v) of the definition of “Event of Default”, its status and what action the Issuer is taking or proposes to take with respect thereto. The Indenture Trustee shall not be deemed to have knowledge of any Event of Default unless a Responsible Officer has actual knowledge thereof or unless written notice of such Event of Default is received by a Responsible Officer and such notice references the Notes, the Trust Estate or this Indenture.

Section 5.02 Acceleration of Maturity; Rescission and Annulment. If an Event of Default should occur and be continuing, then and in every such case the Indenture Trustee at the written direction of the Holders of Notes representing not less than a majority of the aggregate Note Principal Balance of the Notes may declare the Notes to be immediately due and payable, by a notice in writing to the Issuer (and to the Indenture Trustee if such notice is given by Noteholders), and upon any such declaration the unpaid Note Principal Balance of the Notes, together with accrued and unpaid interest thereon through the date of acceleration, shall become immediately due and payable.

At any time after such declaration of acceleration of maturity with respect to an Event of Default has been made and before a judgment or decree for payment of the money due has been obtained by the Indenture Trustee as hereinafter in this Article V provided, Holders of the Notes representing not less than a majority of the aggregate Note Principal Balance of the Notes, by written notice to the Issuer and the Indenture Trustee, may, subject to Section 5.12, waive the related Event of Default and rescind and annul such declaration and its consequences if:

(i) the Issuer has paid or deposited with the Indenture Trustee or Securities Administrator a sum sufficient to pay:

(A) all payments of principal of and interest on the Notes and all other amounts that would then be due hereunder or upon the Notes if the Event of Default giving rise to such acceleration had not occurred;

(B) all sums paid or advanced by the Indenture Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Indenture Trustee and its agents and counsel; and

(C) all Events of Default, other than the nonpayment of the principal of the Notes that has become due solely by such acceleration, have been cured or waived as provided in Section 5.12.

No such rescission shall affect any subsequent default or impair any right consequent thereto.

Section 5.03 Collection of Indebtedness and Suits for Enforcement by Indenture Trustee.

(a) The Issuer covenants that if (i) default is made in the payment of any interest on any Note when the same becomes due and payable, and such default continues for a period of five days, or (ii) default is made in the payment of the principal of or any installment of the principal of any Note when the same becomes due and payable, the Issuer shall, upon demand of the Indenture Trustee, acting at the direction of the Holders of a majority of the aggregate Note Principal Balances of the Notes, pay to the Securities Administrator, for the benefit of the Holders of Notes, the whole amount then due and payable on the Notes for principal and interest, with interest at the applicable Note Interest Rate upon the overdue principal, and in addition thereto such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Indenture Trustee and its agents and counsel.

(b) In case the Issuer shall fail forthwith to pay such amounts upon such demand, the Indenture Trustee, in its own name and as trustee of an express trust, subject to the provisions of Section 10.16 hereof may institute a Proceeding for the collection of the sums so due and unpaid, and may prosecute such Proceeding to judgment or final decree, and may enforce the same against the Issuer or other obligor upon the Notes and collect in the manner provided by law out of the property of the Issuer or other obligor the Notes, wherever situated, the monies adjudged or decreed to be payable.

(c) If an Event of Default occurs and is continuing, the Indenture Trustee, subject to the provisions of Section 10.16 hereof may, as more particularly provided in Section 5.04 hereof, in its discretion, proceed to protect and enforce its rights and the rights of the Noteholders, by such appropriate Proceedings, as directed in writing by Holders of a majority of the aggregate Note Principal Balances of the Notes, to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy or legal or equitable right vested in the Indenture Trustee by this Indenture or by law.

(d) In case there shall be pending, relative to the Issuer or any other obligor upon the Notes or any Person having or claiming an ownership interest in the Trust Estate, Proceedings under Title 11 of the United States Code or any other applicable federal or state bankruptcy, insolvency or other similar law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar official shall have been appointed for or taken possession of the Issuer or its property or such other obligor or Person, or in case of any other comparable judicial Proceedings relative to the Issuer or other obligor upon the Notes, or to the creditors or property of the Issuer or such other obligor, the Indenture Trustee, as directed in writing by Holders of a majority of the aggregate Note Principal Balances of the Notes, irrespective of whether the principal of any Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Indenture Trustee shall have made any demand pursuant to the provisions of this Section, shall be entitled and empowered, by intervention in such Proceedings or otherwise:

(i) to file and prove a claim or claims for the whole amount of principal and interest owing and unpaid in respect of the Notes and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Indenture Trustee (including any claim for reasonable compensation to the Indenture Trustee and each predecessor Indenture Trustee, and their respective agents, attorneys and counsel, and for reimbursement of all expenses and liabilities incurred, and all advances made, by the Indenture Trustee and each predecessor Indenture Trustee, except as a result of negligence or bad faith) and of the Noteholders allowed in such Proceedings;

(ii) unless prohibited by applicable law and regulations, to vote on behalf of the Holders of Notes in any election of a trustee, a standby trustee or Person performing similar functions in any such Proceedings;

(iii) to collect and receive any monies or other property payable or deliverable on any such claims and to distribute all amounts received with respect to the claims of the Noteholders and of the Indenture Trustee on their behalf, and

(iv) to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Indenture Trustee or the Holders of Notes allowed in any judicial proceedings relative to the Issuer, its creditors and its property;

and any trustee, receiver, liquidator, custodian or other similar official in any such Proceeding is hereby authorized by each of such Noteholders to make payments to the Securities Administrator and, in the event that the Indenture Trustee shall consent to the making of payments directly to such Noteholders, to pay to the Indenture Trustee such amounts as shall be sufficient to cover reasonable compensation to the Indenture Trustee, each predecessor Indenture Trustee and their respective agents, attorneys and counsel, and all other expenses and liabilities incurred, and all advances made, by the Indenture Trustee and each predecessor Indenture Trustee.

(e) Nothing herein contained shall be deemed to authorize the Indenture Trustee to authorize or consent to or vote for or accept or adopt on behalf of any Noteholder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof or to authorize the Indenture Trustee to vote in respect of the claim of any Noteholder in any such proceeding except, as aforesaid, to vote for the election of a trustee in bankruptcy or similar Person.

(f) All rights of action and of asserting claims under this Indenture, or under any of the Notes, may be enforced by the Indenture Trustee without the possession of any of the Notes or the production thereof in any trial or other Proceedings relative thereto, and any such action or proceedings instituted by the Indenture Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment, subject to the payment of the expenses, disbursements and compensation of the Indenture Trustee, each predecessor Indenture Trustee and their respective agents and attorneys, shall be for the ratable benefit of the Holders of the Notes, subject to Section 5.05 hereof.

(g) In any Proceedings brought by the Indenture Trustee (and also any Proceedings involving the interpretation of any provision of this Indenture to which the Indenture Trustee shall be a party), the Indenture Trustee shall be held to represent all the Holders of the Notes, and it shall not be necessary to make any Noteholder a party to any such Proceedings.

Section 5.04 Remedies; Priorities. (a) If an Event of Default shall have occurred and be continuing and if an acceleration has been declared and not rescinded pursuant to Section 5.02 hereof, the Indenture Trustee subject to the provisions of Section 10.16 hereof may, and shall, at the written direction of the Holders of a majority of the aggregate Note Principal Balances of the Notes (subject to Section 6.02(k)) do one or more of the following (subject to Section 5.05 hereof):

(i) institute Proceedings in its own name and as trustee of an express trust for the collection of all amounts then payable on the Notes or under this Indenture with respect thereto, whether by declaration or otherwise, enforce any judgment obtained and collect from the Issuer and any other obligor upon such Notes monies adjudged due;

(ii) institute Proceedings from time to time for the complete or partial foreclosure of this Indenture with respect to the Trust Estate;

(iii) exercise any remedies of a secured party under the UCC and take any other appropriate action to protect and enforce the rights and remedies of the Indenture Trustee and the Holders of the Notes; and

(iv) sell the Trust Estate or any portion thereof or rights or interest therein, at one or more public or private sales called and conducted in any manner permitted by law;

provided, however, that the Indenture Trustee may not sell or otherwise liquidate the Trust Estate following an Event of Default, unless (A) the Indenture Trustee obtains the consent of the Holders of 100% of the aggregate Note Principal Balance of the Notes, (B) the proceeds of such sale or liquidation distributable to the Holders of the Notes are sufficient to discharge in full all amounts then due and unpaid upon such Notes for principal and interest or (C) the Indenture Trustee determines that the Mortgage Loans will not continue to provide sufficient funds for the payment of principal of and interest on the applicable Notes as they would have become due if the Notes had not been declared due and payable, and the Indenture Trustee obtains the consent of Holders of 66-2/3% of the aggregate Note Principal Balance of the Notes. In determining such sufficiency or insufficiency with respect to clause (B) and (C), the Indenture Trustee may, but need not, obtain and rely upon an opinion (obtained at the expense of the Trust) of an Independent investment banking or accounting firm of national reputation as to the feasibility of such proposed action and as to the sufficiency of the Trust Estate for such purpose. Notwithstanding the foregoing, so long as an “Event of Default” under the MortgageIT Servicing Agreement has not occurred, any Sale of the Trust Estate shall be made subject to the continued servicing of the Mortgage Loans by the Servicer as provided in the MortgageIT Servicing Agreement.

(b) If the Indenture Trustee or Securities Administrator collects any money or property pursuant to this Article V, the Securities Administrator shall pay out the money or property in the following order:

FIRST: to the Indenture Trustee and the Securities Administrator for amounts due under Section 6.07 hereof or the Sale and Servicing Agreement, to the Master Servicer for amounts due under the Sale and Servicing Agreement, to the Servicer, for amounts due under the MortgageIT Servicing Agreement, and to the Custodian for amounts due under Section 3.4 of the Custodial Agreement;

SECOND: to the Administrator for amounts due under the Administration Agreement;

THIRD: to the Noteholders for amounts due and unpaid on the Notes with respect to interest (not including any Basis Risk Shortfall Carry-Forward Amounts), sequentially, to the Class A-1, M-1, Class M-2, Class M-3, Class M-4, Class B-1, Class B-2 and Class B-3 Noteholders, in that order, according to the amounts due and payable on the Notes for interest;

FOURTH: to the Noteholders for amounts due and unpaid on the Notes with respect to principal, and to each Noteholder ratably, without preference or priority of any kind, according to the amounts due and payable on such Notes for principal, until the Note Principal Balance of each such Class is reduced to zero;

FIFTH: to the Noteholders, first to the Class M-1 Noteholders, second, to the Class M-2 Noteholders, third, to the Class M-3 Noteholders, fourth, to the Class M-4 Noteholders, fifth, to the Class B-1, Class B-2 and Class B-3 Noteholders, in that order, the amount of any related Allocated Realized Loss Amount not previously paid;

SIXTH: to the Noteholders for amounts due and unpaid on the Notes with respect to any related Basis Risk Shortfall Carry-Forward Amounts, first, to the Class A-1 Noteholders, second, to the Class M-1 Noteholders, third, to the Class M-2 Noteholders, fourth, to the Class M-3 Noteholders, fifth, to the Class M-4 Noteholders, sixth, to the Class B-1 Noteholders, seventh, to the Class B-2 Noteholders and eighth, to the Class B-3 Noteholders; and

SEVENTH: to the payment of the remainder, if any to the Certificate Paying Agent on behalf of the Issuer or to any other person legally entitled thereto.

The Securities Administrator may fix a record date and Payment Date for any payment to Noteholders pursuant to this Section 5.04. At least 15 days before such record date, the Securities Administrator shall mail to each Noteholder a notice that states the record date, the Payment Date and the amount to be paid.

Section 5.05 Optional Preservation of the Trust Estate. If the Notes have been declared to be due and payable under Section 5.02 following an Event of Default and such declaration and its consequences have not been rescinded and annulled, the Indenture Trustee may elect to take and maintain possession of the Trust Estate. It is the desire of the parties hereto and the

Noteholders that there be at all times sufficient funds for the payment of principal of and interest on the Notes and other obligations of the Issuer and, the Indenture Trustee shall take such desire into account when determining whether or not to take and maintain possession of the Trust Estate. In determining whether to take and maintain possession of the Trust Estate, the Indenture Trustee may, but need not, obtain and rely upon an opinion of an Independent investment banking or accounting firm of national reputation as to the feasibility of such proposed action and as to the sufficiency of the Trust Estate for such purpose.

Section 5.06 Limitation of Suits. No Holder of any Note shall have any right to institute any Proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless and subject to the provisions of Section 10.16 hereof

(i) such Holder has previously given written notice to the Indenture Trustee of a continuing Event of Default;

(ii) the Holders of not less than 25% of the aggregate Note Principal Balances of the Notes have made a written request to the Indenture Trustee to institute such Proceeding in respect of such Event of Default in its own name as Indenture Trustee hereunder;

(iii) such Holder or Holders have offered to the Indenture Trustee indemnity reasonably satisfactory to it against the costs, expenses and liabilities to be incurred in complying with such request;

(iv) the Indenture Trustee for 60 days after its receipt of such notice of request and offer of indemnity has failed to institute such Proceedings; and

(v) no direction inconsistent with such written request has been given to the Indenture Trustee during such 60-day period by the Holders of a majority of the Note Principal Balances of the Notes.

It is understood and intended that no one or more Holders of Notes shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other Holders of Notes or to obtain or to seek to obtain priority or preference over any other Holders or to enforce any right under this Indenture, except in the manner herein provided.

Subject to the last paragraph of Section 5.11 herein, in the event the Indenture Trustee shall receive conflicting or inconsistent requests and indemnity from two or more groups of Holders of Notes, each representing less than a majority of the Note Principal Balances of the Notes, the Indenture Trustee shall take such action as requested by the Holders representing the highest amount (in the aggregate) of Note Principal Balances notwithstanding any other provisions of this Indenture.

Section 5.07 Unconditional Rights of Noteholders To Receive Principal and Interest. Notwithstanding any other provisions in this Indenture, the Holder of any Note shall have the right, which is absolute and unconditional, to receive payment of the principal of and interest on,

if any, such Note on or after the respective due dates thereof expressed in such Note or in this Indenture and to institute suit for the enforcement of any such payment, and such right shall not be impaired without the consent of such Holder.

Section 5.08 Restoration of Rights and Remedies. If the Indenture Trustee or any Noteholder has instituted any Proceeding to enforce any right or remedy under this Indenture and such Proceeding has been discontinued or abandoned for any reason or has been determined adversely to the Indenture Trustee or to such Noteholder, then and in every such case the Issuer, the Indenture Trustee and the Noteholders shall, subject to any determination in such Proceeding, be restored severally and respectively to their former positions hereunder, and thereafter all rights and remedies of the Indenture Trustee and the Noteholders shall continue as though no such Proceeding had been instituted.

Section 5.09 Rights and Remedies Cumulative. No right or remedy herein conferred upon or reserved to the Indenture Trustee or to the Noteholders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

Section 5.10 Delay or Omission Not a Waiver. No delay or omission of the Indenture Trustee or any Holder of any Note to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article V or by law to the Indenture Trustee or to the Noteholders may be exercised from time to time, and as often as may be deemed expedient, by the Indenture Trustee or by the Noteholders, as the case may be.

Section 5.11 Control By Noteholders. The Holders of a majority of the aggregate Note Principal Balances of Notes shall have the right to direct the time, method and place of conducting any Proceeding for any remedy available to the Indenture Trustee with respect to the Notes or exercising any trust or power conferred on the Indenture Trustee (subject to the Indenture Trustee's right to receive indemnity, as provided herein); provided that:

(i) such direction shall not be in conflict with any rule of law or with this Indenture;

(ii) any direction to the Indenture Trustee to sell or liquidate the Trust Estate shall be by Holders of Notes representing not less than 100% of the Note Principal Balances of the Notes; and

(iii) the Indenture Trustee may take any other action deemed proper by the Indenture Trustee that is not inconsistent with such direction of the Holders of Notes representing a majority of the Note Principal Balances of the Notes.

Notwithstanding the rights of Noteholders set forth in this Section 5.11 the Indenture Trustee need not take any action that it deems unduly prejudicial to any Noteholder or that it determines might subject it to liability.

Section 5.12 Waiver of Past Defaults. Prior to the declaration of the acceleration of the maturity of the Notes as provided in Section 5.02 hereof, the Holders of Notes representing not less than a majority of the aggregate Note Principal Balance of the Notes may waive any past Event of Default and its consequences except an Event of Default (a) with respect to payment of principal of or interest on any of the Notes or (b) in respect of a covenant or provision hereof which cannot be modified or amended without the consent of the Holder of each Note. In the case of any such waiver, the Issuer, the Indenture Trustee and the Holders of the Notes shall be restored to their former positions and rights hereunder, respectively, but no such waiver shall extend to any subsequent or other Event of Default or impair any right consequent thereto.

Upon any such waiver, any Event of Default arising therefrom shall be deemed to have been cured and not to have occurred, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Event of Default or impair any right consequent thereto.

Section 5.13 Undertaking for Costs. All parties to this Indenture agree, and each Holder of any Note and each Beneficial Owner of any interest therein by such ▇▇▇▇▇▇'s or Beneficial Owner's acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Indenture Trustee for any action taken, suffered or omitted by it as Indenture Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys' fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section 5.13 shall not apply to (a) any suit instituted by the Indenture Trustee, (b) any suit instituted by any Noteholder, or group of Noteholders, in each case holding in the aggregate more than 10% of the Note Principal Balances of the Notes or (c) any suit instituted by any Noteholder for the enforcement of the payment of principal of or interest on any Note on or after the respective due dates expressed in such Note and in this Indenture.

Section 5.14 Waiver of Stay or Extension Laws. The Issuer covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead or in any manner whatsoever, claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and the Issuer (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it shall not hinder, delay or impede the execution of any power herein granted to the Indenture Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

Section 5.15 Sale of Trust Estate. (a) The power to effect any sale or other disposition (a “Sale”) of any portion of the Trust Estate pursuant to Section 5.04 hereof is expressly subject to the provisions of Section 5.05 hereof and this Section 5.15. The power to effect any such Sale shall not be exhausted by any one or more Sales as to any portion of the Trust Estate remaining unsold, but shall continue unimpaired until the entire Trust Estate shall have been sold or all amounts payable on the Notes and under this Indenture shall have been paid. The Indenture Trustee may from time to time postpone any public Sale by public announcement made at the time and place of such Sale. The Indenture Trustee hereby expressly waives its right to any amount fixed by law as compensation for any Sale.

(b) The Indenture Trustee shall not in any private Sale sell the Trust Estate, or any portion thereof, unless

(d)

In connection with a Sale of all or any portion of the Trust Estate,

(1) any Holder or Holders of Notes may bid for and purchase the property offered for sale, and upon compliance with the terms of sale may hold, retain and possess and dispose of such property, without further accountability, and may, in paying the purchase money therefor, deliver any Notes or claims for interest thereon in lieu of cash up to the amount which shall, upon distribution of the net proceeds of such sale, be payable thereon, and such Notes, in case the amounts so payable thereon shall be less than the amount due thereon, shall be returned to the Holders thereof after being appropriately stamped to show such partial payment;

(2) the Indenture Trustee, may bid for and acquire the property offered for Sale in connection with any Sale thereof, and, subject to any requirements of, and to the extent permitted by, applicable law in connection therewith, may purchase all or any portion of the Trust Estate in a private sale, and, in lieu of paying cash therefor, may make settlement for the purchase price by crediting the gross Sale price against the sum

of (A) the amount which would be distributable to the Holders of the Notes and Holders of Certificates as a result of such sale on the Payment Date next succeeding the date of such Sale and (B) the expenses of the Sale and of any Proceedings in connection therewith which are reimbursable to it, without being required to produce the Notes in order to complete any such Sale or in order for the net Sale price to be credited against such Notes, and any property so acquired by the Indenture Trustee shall be held and dealt with by it in accordance with the provisions of this Indenture;

(3) the Indenture Trustee shall execute and deliver an appropriate instrument of conveyance, prepared by the Issuer and satisfactory to the Indenture Trustee, transferring its interest in any portion of the Trust Estate in connection with a Sale thereof;

(5) no purchaser or transferee at such a Sale shall be bound to ascertain the Indenture Trustee's authority, inquire into the satisfaction of any conditions precedent or see to the application of any monies.

Section 5.16 Action on Notes. The Indenture Trustee's right to seek and recover judgment on the Notes or under this Indenture shall not be affected by the seeking, obtaining or application of any other relief under or with respect to this Indenture. Neither the lien of this Indenture nor any rights or remedies of the Indenture Trustee or the Noteholders shall be impaired by the recovery of any judgment by the Indenture Trustee against the Issuer or by the levy of any execution under such judgment upon any portion of the Trust Estate or upon any of the assets of the Issuer. Any money or property collected by the Indenture Trustee or the Securities Administrator shall be applied by the Securities Administrator upon receipt in accordance with Section 5.04(b) hereof.

(j) Except for those actions that the Indenture Trustee or the Securities Administrator are required to take hereunder, neither the Indenture Trustee nor the Securities Administrator shall have any obligation or liability to take any action or to refrain from taking any action hereunder in the absence of written direction as provided hereunder.

offered to the Indenture Trustee or the Securities Administrator, as applicable, reasonable security or indemnity reasonably satisfactory to it against the costs, expenses and liabilities which may be incurred therein or thereby. Nothing contained herein shall, however, relieve the Indenture Trustee of the obligation, upon the occurrence of an Event of Default of which a Responsible Officer of the Indenture Trustee has actual knowledge (which has not been cured or waived), to exercise such of the rights and powers vested in it by this Indenture and to use the same degree of care and skill in their exercise as a prudent person would exercise under the circumstances in the conduct of his own affairs.

(q) The Indenture Trustee shall not be deemed to have notice or actual knowledge of any Event of Default unless actually known to a Responsible Officer of the Indenture Trustee or written notice thereof (making reference to this Indenture or the Notes) is received by the Indenture Trustee at the Corporate Trust Office.

Section 6.03 Individual Rights of Indenture Trustee. (a) The Indenture Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuer or its Affiliates with the same rights it would have if it were not Indenture Trustee, subject to the requirements of the Trust Indenture Act.

Neither the Indenture Trustee nor the Securities Administrator shall be responsible for and makes no representation as to the validity or adequacy of this Indenture, the Notes or the other Basic Documents, neither shall be accountable for the Issuer's use of the proceeds from the Notes, and neither shall be responsible for any statement of the Issuer in the Indenture or in any document issued in connection with the sale of the Notes or in the Notes other than, with respect to the Securities Administrator only, the Securities Administrator 's certificate of authentication.

Section 6.05 Notice of Event of Default. Subject to Section 5.01, the Indenture Trustee shall promptly mail to each Noteholder notice of the Event of Default after a Responsible Officer of the Indenture Trustee obtains actual knowledge or written notice of such event, unless such Event of Default shall have been waived or cured. Except in the case of an Event of Default in payment of principal of or interest on any Note, the Indenture Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of Noteholders.

Section 6.06 Reports by Indenture Trustee to Holders and Tax Administration. The Securities Administrator shall deliver to each Noteholder such information as may be required and such other customary information as the Securities Administrator may determine and/or to be required by the Internal Revenue Service or by a federal or state law or rules or regulations to enable such holder to prepare its federal and state income tax returns.

The Securities Administrator shall prepare and file (or cause to be prepared and filed), on behalf of the Owner Trustee, all tax returns (if any) and information reports, tax elections and such annual or other reports of the Issuer as are necessary for preparation of tax returns and information reports as provided in Section 5.03 of the Trust Agreement, including without limitation Form 1099. All tax returns and information reports shall be signed by the Owner Trustee as provided in Section 5.03 of the Trust Agreement.

Section 6.07 Compensation. An annual fee shall be paid to the Indenture Trustee by the Master Servicer pursuant to a separate agreement between the Indenture Trustee and the Master Servicer. In addition, the Indenture Trustee and the Securities Administrator will each be entitled to recover from the Payment Account pursuant to Section 4.05(a) of the Sale and Servicing Agreement all reasonable out-of-pocket expenses, disbursements and advances and the expenses of the Indenture Trustee and the Securities Administrator, respectively, in connection

with any breach of this Agreement or any claim or legal action (including any pending or threatened claim or legal action) or otherwise incurred or made by the Indenture Trustee or the Securities Administrator, respectively, in the administration of the trusts hereunder (including the reasonable compensation, expenses and disbursements of its counsel) except any such expense, disbursement or advance as may arise from its own negligence or intentional misconduct or which is the responsibility of the Noteholders as provided herein. Such compensation and reimbursement obligation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust. Additionally, each of the Indenture Trustee and the Securities Administrator and any director, officer, employee or agent of the Indenture Trustee or the Securities Administrator shall be indemnified by the Trust and held harmless against any loss, liability or expense (including reasonable attorney's fees and expenses) incurred in the administration of this Agreement (other than its ordinary out of pocket expenses incurred hereunder) or in connection with any claim or legal action relating to (a) the Basic Documents or (b) the Notes, other than any loss, liability or expense incurred by reason of its own negligence or intentional misconduct, or which is the responsibility of the Noteholders as provided herein. Notwithstanding the foregoing, the Indenture Trustee and any director, officer, employee or agent of the Indenture Trustee shall also be indemnified by the Trust and held harmless against any loss, liability or expense (including reasonable attorney's fees and expenses) incurred in the administration of the Corridor Contract or in connection with any claim or legal action relating to the Corridor Contract which is the responsibility of the Noteholders as provided herein.

The Issuer's payment obligations to the Indenture Trustee and Securities Administrator pursuant to this Section 6.07 shall survive the discharge of this Indenture and the termination or resignation of the Indenture Trustee or Securities Administrator. When the Indenture Trustee or the Securities Administrator incurs expenses after the occurrence of an Event of Default with respect to the Issuer, the expenses are intended to constitute expenses of administration under Title 11 of the United States Code or any other applicable federal or state bankruptcy, insolvency or similar law.

Section 6.08 Replacement of Indenture Trustee and the Securities Administrator. No resignation or removal of the Indenture Trustee or the Securities Administrator and no appointment of a successor Indenture Trustee or successor Securities Administrator shall become effective until the acceptance of appointment by the successor Indenture Trustee or successor Securities Administrator pursuant to this Section 6.08. The Indenture Trustee or the Securities Administrator may resign at any time by so notifying the Issuer. Any resignation or removal of the Securities Administrator shall result in the automatic removal of the Master Servicer to the extent that ▇▇▇▇▇ Fargo Bank, N.A. is both the Securities Administrator and Master Servicer. Holders of a majority of Note Principal Balances of the Notes may remove either of the Indenture Trustee or the Securities Administrator by so notifying the Indenture Trustee or the Securities Administrator and may appoint a successor Indenture Trustee or successor Securities Administrator. The Issuer shall remove the Indenture Trustee or the Securities Administrator, as applicable, if:

(i) the Indenture Trustee or the Securities Administrator fails to comply with Section 6.11 hereof;

(ii) the Indenture Trustee or the Securities Administrator is adjudged a bankrupt or insolvent;

(iii) a receiver or other public officer takes charge of the Indenture Trustee or the Securities Administrator or its property; or

(iv) the Indenture Trustee or the Securities Administrator otherwise becomes incapable of acting.

If the Indenture Trustee or the Securities Administrator resigns or is removed or if a vacancy exists in the office of the Indenture Trustee or the Securities Administrator for any reason (the Indenture Trustee or the Securities Administrator in such event being referred to herein as the retiring Indenture Trustee or the retiring Securities Administrator), the Issuer shall promptly appoint a successor Indenture Trustee or successor Securities Administrator.

Each of a successor Indenture Trustee or successor Securities Administrator shall deliver a written acceptance of its appointment to the retiring Indenture Trustee or the retiring Securities Administrator, as applicable, and to the Issuer. Thereupon, the resignation or removal of the retiring Indenture Trustee or the retiring Securities Administrator shall become effective, and the successor Indenture Trustee or successor Securities Administrator shall have all the rights, powers and duties of the Indenture Trustee or the Securities Administrator, as applicable, under this Indenture. The successor Indenture Trustee or successor Securities Administrator shall each mail a notice of its succession to Noteholders. The retiring Indenture Trustee or the retiring Securities Administrator shall promptly transfer all property held by it as Indenture Trustee or Securities Administrator, as applicable, to the successor Indenture Trustee or successor Securities Administrator.

If a successor Indenture Trustee or successor Securities Administrator does not take office within 60 days after the retiring Indenture Trustee or the retiring Securities Administrator, as applicable, resigns or is removed, the retiring Indenture Trustee or the retiring Securities Administrator, the Issuer or the Holders of a majority of Note Principal Balances of the Notes may petition any court of competent jurisdiction for the appointment of a successor Indenture Trustee or successor Securities Administrator.

Notwithstanding the replacement of the Indenture Trustee or the Securities Administrator pursuant to this Section, the Issuer's obligations under Section 6.07 shall continue for the benefit of the retiring Indenture Trustee or the retiring Securities Administrator.

Section 6.09 Successor Indenture Trustee and Securities Administrator by ▇▇▇▇▇▇. If the Indenture Trustee or the Securities Administrator consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business or assets to, another corporation or banking association, the resulting, surviving or transferee corporation, without any further act, shall be the successor Indenture Trustee or successor Securities Administrator, as applicable; provided, that such corporation or banking association shall be otherwise qualified and eligible

under Section 6.11 hereof. The Indenture Trustee and the Securities Administrator shall each provide the Rating Agencies with prior written notice of any such transaction.

If at the time such successor or successors by merger, conversion or consolidation to the Indenture Trustee shall succeed to the trusts created by this Indenture and any of the Notes shall have been authenticated but not delivered, any such successor to the Indenture Trustee may adopt the certificate of authentication of any predecessor trustee and deliver such Notes so authenticated; and if at that time any of the Notes shall not have been authenticated, any successor to the Indenture Trustee may authenticate such Notes either in the name of any predecessor hereunder or in the name of the successor to the Indenture Trustee; and in all such cases such certificates shall have the full force which it is in the Notes or in this Indenture provided that the certificate of the Indenture Trustee shall have.

Section 6.10 Appointment of Co-Indenture Trustee or Separate Indenture Trustee. (a) Notwithstanding any other provisions of this Indenture, at any time, for the purpose of meeting any legal requirement of any jurisdiction in which any part of the Trust Estate may at the time be located, the Indenture Trustee shall have the power and may execute and deliver all instruments to appoint one or more Persons to act as a co-trustee or co-trustees, or separate trustee or separate trustees, of all or any part of the Trust Estate, and to vest in such Person or Persons, in such capacity and for the benefit of the Noteholders, such title to the Trust Estate, or any part hereof, and, subject to the other provisions of this Section, such powers, duties, obligations, rights and trusts as the Indenture Trustee may consider necessary or desirable.

(ii) no trustee hereunder shall be personally liable by reason of any act or omission of any other trustee hereunder; and

if given to each of them. Every instrument appointing any separate trustee or co-trustee shall refer to this Indenture and the conditions of this Article VI. Each separate trustee and co-trustee, upon its acceptance of the trusts conferred, shall be vested with the estates or property specified in its instrument of appointment, either jointly with the Indenture Trustee or separately, as may be provided therein, subject to all the provisions of this Indenture, specifically including every provision of this Indenture relating to the conduct of, affecting the liability of, or affording protection to, the Indenture Trustee. Every such instrument shall be filed with the Indenture Trustee.

If any separate trustee or co-trustee shall die, become incapable of acting, resign or be removed, all of its estates, properties, rights, remedies and trusts shall vest in and be exercised by the Indenture Trustee, to the extent permitted by law, without the appointment of a new or successor trustee.

Any such certificate of an Authorized Officer or Opinion of Counsel may be based, insofar as it relates to factual matters, upon a certificate or opinion of, or representations by, an officer or officers of the Seller or the Issuer, stating that the information with respect to such factual matters is in the possession of the Seller or the Issuer, unless such

counsel knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to such matters are erroneous.

Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated and form one instrument.

Whenever in this Indenture, in connection with any application or certificate or report to the Indenture Trustee, it is provided that the Issuer shall deliver any document as a condition of the granting of such application, or as evidence of the Issuer's compliance with any term hereof, it is intended that the truth and accuracy, at the time of the granting of such application or at the effective date of such certificate or report (as the case may be), of the facts and opinions stated in such document shall in such case be conditions precedent to the right of the Issuer to have such application granted or to the sufficiency of such certificate or report. The foregoing shall not, however, be construed to affect the Indenture Trustee's right to rely upon the truth and accuracy of any statement or opinion contained in any such document as provided in Article VI.

Section 10.03 Acts of Noteholders. (a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Noteholders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Noteholders in person or by agents duly appointed in writing; and except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Indenture Trustee, and, where it is hereby expressly required, to the Issuer. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Noteholders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and (subject to Section 6.01 hereof) conclusive in favor of the Indenture Trustee and the Issuer, if made in the manner provided in this Section 10.03 hereof.

(b) The fact and date of the execution by any person of any such instrument or writing may be proved in any manner that the Indenture Trustee deems sufficient.

(c)

The ownership of Notes shall be proved by the Note Registrar.

(d) Any request, demand, authorization, direction, notice, consent, waiver or other action by the Holder of any Notes shall bind the Holder of every Note issued upon the registration thereof or in exchange therefor or in lieu thereof, in respect of anything done, omitted or suffered to be done by the Indenture Trustee or the Issuer in reliance thereon, whether or not notation of such action is made upon such Note.

Section 10.04 Notices etc., to Indenture Trustee, Securities Administrator, Issuer and Rating Agencies. Any request, demand, authorization, direction, notice, consent, waiver or act of Noteholders or other documents provided or permitted by this Indenture shall be in writing and if such request, demand, authorization, direction, notice, consent, waiver or act of Noteholders is to be made upon, given or furnished to or filed with:

(i) the Indenture Trustee by any Noteholder or by the Issuer shall be sufficient for every purpose hereunder if in writing and made, given, furnished or filed to or with the Indenture Trustee at the Corporate Trust Office. The Indenture Trustee shall promptly transmit any notice received by it from the Noteholders to the Issuer;

(ii) the Securities Administrator by any Noteholder or by the Issuer shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing to or with the Securities Administrator at ▇▇▇▇▇ Fargo Bank, National Association, P.O. Box 98, Columbia Maryland 21046 (or, in the case of overnight deliveries, ▇▇▇▇ ▇▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇ ▇▇▇▇▇) (Attention: Corporate Trust Services - MortgageIT 2005-4), facsimile no.: (▇▇▇) ▇▇▇-▇▇▇▇, or such other address as may hereafter be furnished to the other parties hereto in writing. The Securities Administrator shall promptly transmit any notice received by it from the Noteholders to the Issuer

(iii) the Issuer by the Indenture Trustee or by any Noteholder shall be sufficient for every purpose hereunder if in writing and mailed first-class, postage prepaid to the Issuer addressed to: MortgageIT Trust 2005-4, in care of Wilmington Trust Company, ▇▇▇▇▇▇ Square North, ▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇ ▇▇▇▇▇-▇▇▇▇, Attention: Corporate Trust Administration, or at any other address previously furnished in writing to the Indenture Trustee by the Issuer. The Issuer shall promptly transmit any notice received by it from the Noteholders to the Indenture Trustee.

Notices required to be given to the Rating Agency by the Issuer, the Indenture Trustee, the Securities Administrator or the Owner Trustee shall be in writing, mailed first-class postage pre-paid, to, in the case of Standard & Poor's, at the following address: Standard & Poor's, ▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇^▇▇ ▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, Attention of Asset Backed Surveillance Department, in the case of Moody's, at the following address: ▇▇▇▇▇'▇ Investors Service, Inc., ▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇; or at such other address as shall be designated by written notice to the other parties.

Section 10.05 Notices to Noteholders; Waiver. Where this Indenture provides for notice to Noteholders of any event, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class, postage prepaid to each Noteholder affected by such event, at such Person's address as it appears on the Note Register, not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice. In any case where notice to Noteholders is given by mail, neither the failure to mail such notice nor any defect in any notice so mailed to any particular Noteholder shall affect the sufficiency of such notice with respect to other Noteholders, and any notice that is mailed in the manner herein provided shall conclusively be presumed to have been duly given regardless of whether such notice is in fact actually received.

Where this Indenture provides for notice in any manner, such notice may be waived in writing by any Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Noteholders shall be filed with the Indenture Trustee but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such a waiver.

In case, by reason of the suspension of regular mail service as a result of a strike, work stoppage or similar activity, it shall be impractical to mail notice of any event to Noteholders when such notice is required to be given pursuant to any provision of this Indenture, then any manner of giving such notice as shall be satisfactory to the Indenture Trustee shall be deemed to be a sufficient giving of such notice.

Where this Indenture provides for notice to the Rating Agencies, failure to give such notice shall not affect any other rights or obligations created hereunder, and shall not under any circumstance constitute an Event of Default.

Section 10.06 Conflict with Trust Indenture Act. If any provision hereof limits, qualifies or conflicts with another provision hereof that is required to be included in this Indenture by any of the provisions of the Trust Indenture Act, such required provision shall control.

The provisions of TIA §§ 310 through 317 that impose duties on any Person (including the provisions automatically deemed included herein unless expressly excluded by this Indenture) are a part of and govern this Indenture, whether or not physically contained herein.

Section 10.07 Effect of Headings. The Article and Section headings herein are for convenience only and shall not affect the construction hereof.

Section 10.08 Successors and Assigns. All covenants and agreements in this Indenture and the Notes by the Issuer shall bind its successors and assigns, whether so expressed or not. All agreements of the Indenture Trustee in this Indenture shall bind its successors, co-trustees and agents.

Section 10.09 Separability. In case any provision in this Indenture or in the Notes shall be invalid, illegal or unenforceable, the validity, legality, and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

Section 10.10

[Reserved].

Section 10.11 Legal Holidays. In any case where the date on which any payment is due shall not be a Business Day, then (notwithstanding any other provision of the Notes or this Indenture) payment need not be made on such date, but may be made on the next succeeding Business Day with the same force and effect as if made on the date on which nominally due, and no interest shall accrue for the period from and after any such nominal date.

Section 10.12 GOVERNING LAW. THIS INDENTURE SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REFERENCE TO ITS CONFLICT OF LAW PROVISIONS (EXCEPT FOR SECTION 5-1401 OF THE GENERAL OBLIGATIONS LAW), AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

Section 10.13 Counterparts. This Indenture may be executed in any number of counterparts, each of which so executed shall be deemed to be an original, but all such counterparts shall together constitute but one and the same instrument.

Section 10.14 Recording of Indenture. If this Indenture is subject to recording in any appropriate public recording offices, such recording is to be effected by the Issuer and at its expense accompanied by an Opinion of Counsel at its expense (which may be counsel to the Issuer, the Indenture Trustee or any other counsel reasonably acceptable to the Indenture Trustee) to the effect that such recording is necessary either for the protection of the Noteholders or any other Person secured hereunder or for the enforcement of any right or remedy granted to the Indenture Trustee under this Indenture.

Section 10.15 Issuer Obligation. No recourse may be taken, directly or indirectly, with respect to the obligations of the Issuer, the Securities Administrator, the Owner Trustee or the Indenture Trustee on the Notes or under this Indenture or any certificate or other writing delivered in connection herewith or therewith, against (i) the Indenture Trustee or the Owner Trustee in its individual capacity, (ii) any owner of a beneficial interest in the Issuer or (iii) any partner, owner, beneficiary, agent, officer, director, employee or agent of the Indenture Trustee or the Owner Trustee in its individual capacity, any holder of a beneficial interest in the Issuer, the Securities Administrator, the Owner Trustee or the Indenture Trustee or of any successor or assign of the Indenture Trustee or the Owner Trustee in its individual capacity, except as any such Person may have expressly agreed (it being understood that the Indenture Trustee and the Owner Trustee have no such obligations in their individual capacity) and except that any such partner, owner or beneficiary shall be fully liable, to the extent provided by applicable law, for any unpaid consideration for stock, unpaid capital contribution or failure to pay any installment or call owing to such entity. For all purposes of this Indenture, in the performance of any duties or obligations of the Issuer hereunder, the Owner Trustee shall be subject to, and entitled to the benefits of, the terms and provisions of Article VI, VII and VIII of the Trust Agreement.

Section 10.16 No Petition. The Indenture Trustee and the Securities Administrator, by entering into this Indenture, each Noteholder, by accepting a Note, and each Certificateholder, by accepting a Certificate, hereby covenant and agree that they will not at any time prior to one year from the date of termination hereof, institute against the Depositor or the Issuer, or join in any institution against the Depositor or the Issuer of, any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings, or other proceedings under any United States federal or state bankruptcy or similar law in connection with any obligations relating to the Notes, this Indenture or any of the Basic Documents; provided however, that nothing herein shall prohibit the Indenture Trustee from filing proofs of claim in any proceeding.

Section 10.17 Inspection. The Issuer agrees that, at its expense, on reasonable prior notice, it shall permit any representative of the Indenture Trustee or the Securities Administrator, during the Issuer's normal business hours, to examine all the books of account, records, reports and other papers of the Issuer, to make copies and extracts therefrom, to cause such books to be audited by Independent certified public accountants, and to discuss the Issuer's affairs, finances and accounts with the Issuer's officers, employees, and Independent certified public accountants, all at such reasonable times and as often as may be reasonably requested. The Indenture Trustee shall cause its representatives to hold in confidence all such information except to the extent disclosure may be required by law, regulation, judicial process or made to the Indenture Trustee's auditors, regulators, attorneys or other governmental authorities and except to the extent that the Indenture Trustee or the Securities Administrator may reasonably determine that such disclosure is consistent with its obligations hereunder.

IN WITNESS WHEREOF, the Issuer, the Indenture Trustee and the Securities Administrator have caused their names to be signed hereto by their respective officers thereunto duly authorized, all as of the day and year first above written.

MortgageIT Trust 2005-4 (the “Issuer”), a Delaware statutory trust, for value received, hereby promises to pay to Cede & Co. or registered assigns, the principal sum of ($_________________) in monthly installments on the twenty-fifth day of each month or, if such day is not a Business Day, the next succeeding Business Day (each a “Payment Date”), commencing in September 2005 and ending on or before the Payment Date occurring in October 2035 (the “Final Scheduled Payment Date”) and to pay interest on the Note Principal Balance of this Note (this “Note”) outstanding from time to time as provided below.

This Note is one of a duly authorized issue of the Issuer's Mortgage-Backed Notes, Series 2005-4 (the “Notes”), issued under an Indenture dated as of August 24, 2005 (the “Indenture”), among the Issuer, ▇▇▇▇▇ Fargo Bank, National Association, as securities administrator (the “Securities Administrator”) and Deutsche Bank National Trust Company, as indenture trustee (the “Indenture Trustee”, which term includes any successor Indenture Trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights thereunder of the Issuer, the Indenture Trustee, and the Holders of the Notes and the terms upon which the Notes are to be authenticated and delivered. All terms used in this Note which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

Payments of principal and interest on this Note will be made on each Payment Date to the Noteholder of record as of the related Record Date. The “Note Principal Balance” of a Note as of any date of determination is equal to the initial Note Principal Balance thereof, reduced by the aggregate of all amounts previously paid with respect to such Note on account of principal and the aggregate amount of cumulative Realized Losses allocated to such Note on all prior Payment Dates.

The principal of, and interest on, this Note are due and payable as described in the Indenture, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. All payments made by the Issuer with respect to this Note shall be equal to this Note's pro rata share of the aggregate payments on all Class A-1 Notes as described above, and shall be applied as between interest and principal as provided in the Indenture.

All principal and interest accrued on the Notes, if not previously paid, will become finally due and payable at the Final Scheduled Payment Date.

The Notes are subject to redemption in whole, but not in part, by the Majority Certificateholder on any Payment Date on or after the Payment Date on which the aggregate Scheduled Principal Balance of the Mortgage Loans as of the end of the prior Due Period is less than or equal to 20% of the aggregate Scheduled Principal Balance of the Mortgage Loans as of the Cut-off Date.

The Issuer shall not be liable upon the indebtedness evidenced by the Notes except to the extent of amounts available from the Trust Estate which constitutes security for the payment of the Notes. The assets included in the Trust Estate will be the sole source of payments on the Class A-1 Notes, and each Holder hereof, by its acceptance of this Note, agrees that (i) such Note will be limited in right of payment to amounts available from the Trust Estate as provided in the Indenture and (ii) such Holder shall have no recourse to the Issuer, the Securities Administrator, the Owner Trustee, the Indenture Trustee, the Depositor, the Master Servicer, the Servicer or any of their respective affiliates, or to the assets of any of the foregoing entities, except the assets of the Issuer pledged to secure the Class A-1 Notes pursuant to the Indenture and the rights conveyed by the Issuer under the Indenture.

Any payment of principal or interest payable on this Note which is punctually paid on the applicable Payment Date shall be paid to the Person in whose name such Note is registered at the close of business on the Record Date for such Payment Date by check mailed to such person's address as it appears in the Note Register on such Record Date, except for the final installment of principal and interest payable with respect to such Note, which shall be payable as provided below. Notwithstanding the foregoing, upon written request with appropriate instructions by the Holder of this Note delivered to the Securities Administrator at least five Business Days prior to the Record Date, any payment of principal or interest, other than the final installment of principal or interest, shall be made by wire transfer to an account in the United States designated by such Holder. All scheduled reductions in the principal amount of a Note (or one or more predecessor Notes) effected by payments of principal made on any Payment Date shall be binding upon all Holders of this Note and of any note issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof, whether or not such payment is noted on such Note. The final payment of this Note shall be payable upon presentation and surrender thereof on or after the Payment Date thereof at the office designated by the Securities Administrator or the office or agency of the Issuer maintained by it for such purpose pursuant to Section 3.02 of the Indenture.

Subject to the foregoing provisions, each Note delivered under the Indenture, upon registration of transfer of or in exchange for or in lieu of any other Note shall carry the right to unpaid principal and interest that were carried by such other Note.

If an Event of Default as defined in the Indenture shall occur and be continuing with respect to the Notes, the Notes may become or be declared due and payable in the manner and with the effect provided in the Indenture. If any such acceleration of maturity occurs prior to the payment of the entire unpaid Note Principal Balance of the Notes, the amount payable to the Holder of this Note will be equal to the sum of the unpaid Note Principal Balance of the Notes, together with accrued and unpaid interest thereon as described in the Indenture. The Indenture

provides that, notwithstanding the acceleration of the maturity of the Notes, under certain circumstances specified therein, all amounts collected as proceeds of the Trust Estate securing the Notes or otherwise shall continue to be applied to payments of principal of and interest on the Notes as if they had not been declared due and payable.

The Holder of this Note or Beneficial Owner of any interest herein is deemed to represent that either (1) it is not acquiring the Note with Plan Assets or (2) (A) the acquisition, holding and transfer of a Note will not give rise to a nonexempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code and (B) the Notes are rated investment grade or better and such person believes that the Notes are properly treated as indebtedness without substantial equity features for purposes of the DOL Regulations, and agrees to so treat the Notes. Alternatively, regardless of the rating of the Notes, such person may provide the Securities Administrator and the Owner Trustee with an Opinion of Counsel, which Opinion of Counsel will not be at the expense of the Issuer, the Seller, any Underwriter, the Owner Trustee, the Indenture Trustee, the Securities Administrator, the Master Servicer, the Servicer or any successor servicer which opines that the acquisition, holding and transfer of such Note or interest therein is permissible under applicable law, will not constitute or result in a non-exempt prohibited transaction under ERISA or Section 4975 of the Code and will not subject the Issuer, the Seller, the Depositor, any Underwriter, the Owner Trustee, the Indenture Trustee, the Master Servicer, the Securities Administrator or the Servicer to any obligation in addition to those undertaken in the Indenture.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Note may be registered on the Note Register of the Issuer. Upon surrender for registration of transfer of, or presentation of a written instrument of transfer for, this Note at the office or agency designated by the Issuer pursuant to the Indenture, accompanied by proper instruments of assignment in form satisfactory to the Securities Administrator, one or more new Notes of any authorized denominations and of a like aggregate initial Note Principal Balance, will be issued to the designated transferee or transferees.

Prior to the due presentment for registration of transfer of this Note, the Issuer, the Indenture Trustee, the Securities Administrator and any agent of the Issuer, the Securities Administrator or the Indenture Trustee may treat the Person in whose name this Note is registered as the owner of such Note (i) on the applicable Record Date for the purpose of making payments and interest of such Note, and (ii) on any other date for all other purposes whatsoever, as the owner hereof, whether or not this Note be overdue, and none of the Issuer, the Securities Administrator, the Indenture Trustee or any such agent of the Issuer, the Securities Administrator or the Indenture Trustee shall be affected by notice to the contrary.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Issuer and the rights of the Holders of the Notes under the Indenture at any time by the Issuer and the Holders of a majority of all Notes at the time outstanding. The Indenture also contains provisions permitting the Holders of Notes representing specified percentages of the aggregate Note Principal Balance of the Notes on behalf of the Holders of all the Notes, to waive any past Default under the Indenture and its consequences. Any such waiver by the Holder, at the time of the giving thereof, of this Note (or any one or more predecessor Notes) shall bind the Holder of every Note issued upon the

registration of transfer hereof or in exchange hereof or in lieu hereof, whether or not notation of such consent or waiver is made upon such Note. The Indenture also permits the Issuer, the Indenture Trustee and the Securities Administrator to amend or waive certain terms and conditions set forth in the Indenture without the consent of the Holders of the Notes issued thereunder.

Initially, the Notes will be registered in the name of Cede & Co. as nominee of DTC, acting in its capacity as the Depository for the Notes. The Notes will be delivered by the clearing agency in denominations as provided in the Indenture and subject to certain limitations therein set forth. The Notes are exchangeable for a like aggregate initial Note Principal Balance of Notes of different authorized denominations, as requested by the Holder surrendering same.

Unless the Certificate of Authentication hereon has been executed by the Securities Administrator by manual signature, this Note shall not be entitled to any benefit under the Indenture, or be valid or obligatory for any purpose.

AS PROVIDED IN THE INDENTURE, THIS NOTE AND THE INDENTURE CREATING THIS NOTE SHALL BE CONSTRUED IN ACCORDANCE WITH, AND GOVERNED BY, THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED THEREIN.

IN WITNESS WHEREOF, the Issuer has caused this instrument to be duly executed by Wilmington Trust Company, not in its individual capacity but solely as Owner Trustee.
